Selection of Harness Materials

The quality of the wire harness material directly affects the quality of the wire harness, and the selection of the wire harness material is related to the quality and service life of the wire harness. How to distinguish the quality of the wiring harness? Understand the material of the wire harness to understand. The following is the information of wire harness selection.

The wiring harness is generally composed of wires, insulating sheaths, terminals and wrapping materials.

1. Material selection of terminals

The copper used for the terminal material (copper parts) is mainly brass and bronze (the hardness of brass is slightly lower than that of bronze), of which brass accounts for a larger proportion. In addition, different coatings can be selected according to different needs.

2. the choice of insulating sheath

The commonly used materials for sheath materials (plastic parts) are PA6, PA66, ABS, PBT, pp, etc. According to the actual situation, flame retardant or reinforcing materials can be added to the plastic to achieve the purpose of reinforcement or flame retardant, such as adding glass fiber reinforcement.

3. Selection of wire harness wires

According to the different use environment, select the corresponding wire material.

4. the choice of dressing materials

The wire harness wrapping plays the role of wear resistance, flame retardant, anti-corrosion, preventing interference, reducing noise, and beautifying the appearance. Generally, the wrapping material is selected according to the working environment and space size. In the choice of dressing materials, there are usually tapes, corrugated pipes, PVC pipes, etc.
